Patented Aug. 14, 1934 UNITED STATES PATENT OFFlCE LENS Application May16, 1932, Serial No. 611,652 Renewed January 8, 1934 1 Claim.

This invention relates to lens for headlights and has for the primaryobject, the provision of an integral hood to the lens extending into theheadlight above the illuminating means for preventing undesirable glareor blinding rays of light from shining into the eyes of personsapproaching the headlight.

With this and other objects in view, this invention consists in certainnovel features of conl0 struction, combination and arrangement of partsto be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawing, in which Figure 1 isa rear elevation illustrating a lens constructed in accordance with myinvention.

Figure 2 is a vertical sectional view illustrating a lens applied to aheadlight.

Referring in detail to the drawing, the numeral 1 indicates a headlightcasing in which is mounted a reflector 2 of a conventional type carryinga socket 3 for supporting an electric lamp 4. The front of the casing land the reflector 2 are closed by a transparent plate 5 on which isformed a hood 6 of a material in accordance with the material or" theplate. The hood 6 extends upwardly and rearwardly within the reflectorand is transversely curved as shown in Figure 2 and has its outer facesilvered for forming the inner face thereof as that of a mirror forreflecting light rays downwardly. The side edges and the free end of thehood are spaced slightly from the walls of the reflector so that a smallamount of light rays from the electric lamp may pass about the hood toprovide a subdued light about the upper half of the headlight. The hoodis adapted to direct the light rays in a fixed downward direction inaccordance with the radius of curvature of the hood. The lower end ofthe hood is in alignment with the top of the electric lamp so that thelight rays from the headlight will be directed outwardly and downwardlythrough the lens below the hood to prevent blinding of approachingpersons or undesirable glare from the headlight.

While I have shown and described the preferred embodiment of myinvention, it will be understood that minor changes in construction,combination and arrangement of parts may be made without departing fromthe spirit and scope of my invention, as claimed.

Having thus described my invention, what I claim is:-

In combination with a headlight casing having a reflector and anilluminating lamp carried thereby, a transparent panel closing thereflector I5 and arranged in advance of the lamp, a hood or" the samematerial and thickness as that of the plate integral therewith andmerging with the latter along a straight line disposed above thelongitudinal axis of the casing and above the 81 lamp, said hood havingits lower portion from its line of merger with the plate inclinedupwardly at an acute angle to the inner face of the plate and having itsupper portion curved upwardly and then downwardly from said face of 85the plate to overhang the lamp, the free edges of said hood being spaceda slight distance from the walls of the reflector and said edges beingdisposed above the lamp, and a mirror-forming coating applied to therear face of the hood next to said plate.
